- ventral spinal cord development
The process whose specific outcome is the progression of the ventral region of the spinal cord over time, from its formation to the mature structure. The neurons of the ventral region of the mature spinal cord participate in motor output.
- ventral spinal cord interneuron fate commitment
The process in which the developmental fate of a cell becomes restricted such that it will develop into a ventral spinal cord interneuron. Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses.
- ventral spinal cord interneuron fate determination
The process in which a cell becomes capable of differentiating autonomously into a ventral spinal cord interneuron regardless of its environment; upon determination, the cell fate cannot be reversed. Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses.
- somatic motor neuron fate commitment
The commitment of unspecified motor neurons to specific motor neuron cell along the anterior-posterior axis of the spinal cord and their capacity to differentiate into specific motor neurons.
- ventral spinal cord interneuron differentiation
The process in which neuroepithelial cells in the neural tube acquire specialized structural and/or functional features of ventral spinal cord interneurons. Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses. Differentiation includes the processes involved in commitment of a cell to a specific fate.
- C bouton
Synaptic bouton found in spinal cord on the soma and proximal dendrites of motor neurons.
- spinal cord motor neuron migration
The orderly movement of a spinal cord motor neuron from one site to another. A spinal cord motor neuron is a motor neuron that passes from the spinal cord toward or to a muscle and conducts an impulse that causes movement.
- spinal cord motor neuron differentiation
The process in which neuroepithelial cells in the ventral neural tube acquire specialized structural and/or functional features of motor neurons. Motor neurons innervate an effector (muscle or glandular) tissue and are responsible for transmission of motor impulses from the brain to the periphery. Differentiation includes the processes involved in commitment of a cell to a specific fate.
